ORE sINTER INti CAR Filed June 12 1930 2 Sheets-Shem l Patented 'Oct; 20, 1 931 I Application fi'ieagniaefie,

This invention relatesito improvements in sintering machines, moreparticularly to an improved car structureforthe carrying out of asintering process. a I a 5 The primary object of the present inventionis to provide a sintering car 'for metalliferous sulphur bearing ore forthe intermittent burning of such ,ores' and'so designed as to produceaneven forced draft through 19 the ore after the same hasbeen fired sothat the reduction of the ore will take place evenly and thoroughly. lax7 1; I I

' Other objects'and advantages of the pres-' ent invention will becomeapparent as the description of the same 'proceedsand the inventio'n willbe best understood from a conside'ration of the followingdetaileddescrip tion taken in connection with the accompanyin drawings'formin'gfpart of this 'speci:

V 29 fication, with the understanding; however,

that the invention is not confined to any strict conformity with theshowing of the drawings but may be changed ormodified so long as suchchangesor modifications mark no material departure from the salientfeatures of the invention as expressed in the appended claims.

This car, asshown, comprises a base portion made up of a pair of channel beams 2which'are mounted inanysuitable; manner upon theaxles 3 oftwo or morepairs-of flanged wheels, ieach of which is indicatedby the numeral 4These wheels are mounted to rotateion suitable-bearings about itheaizles3 which-bear- 1930. SeriaI no. aea to a 5 the upwardly and outwardlydirected side wall sheets 5 which form the lower portionof the car body,these sheetsbeing of'lsteelof suitable weight. At each end "ofthe carstructure an end sheet '6 connects the end edgesof the side sheets 5'andcoacts With a bottom 7. to close the lower part of the car structurewhich constitutes a draft chamber.

One end wall 6 of the car body is provided with a draftwaperture 8 aboutwhich on, the outer face of the end wall is a beveled flange ,9. rEach'ofithe side walls 5 terminates at its 5 7 upper portion ina;vertically disposed, sec-. tion-10 and the inner. face of each ofthese vertical sections has securedthereto a-cast .metalliner 11'. Eachof-the end walls also has secured to itsinner face and adjacent the topthereof aliner 12 similar to the liners '11, the lower'edgesofltheliners 12 being in the same plane. as the lower edges of theliners 11." l 7 7 Eachoff the liners 11 uponftheside walls of the carbodyis provided with an inwardly projecting longitudinal rib 13 andabove this ribzthere are formed at spaced intervals vertical slots ,Theslots 14: receive the ends --of the transverse grate bars 15 which-restupon the flanges 13 ,in the manner-shown.

o Eachiof these grate'barshas fixed transversely of the top-edge thereofa number of plates 516 the ends of which come into abutting re-..lation. withtheplates upon the adjacent bars. Disposed beneaththegrate bars 15 and in relatively close relation thereto is a trans-.averse horizontal plate 117 which isprovided fi thro11gh011t*Withapertures 18. f j "rSp aced from and disposed beneath the ap-'erturedplate-17 is asecond plate 19 which,

' like the plate 17,- extends the full length and 'widthof the'carbody,the edges of this plate Lbeing'turned to provide the flanges/20 whichare bolted or *otherwise secured to the in- ,clined portions" of theside walls 5. This plate 17- isprovided with short transversely 7extending slots 21' and inaddition is upwardly curved or cambered as isclearly shown men I V which it is mounted, to bring the flange 9 of Inoperation the ore to be treated, together with the necessary combustiblematerial mixed therewith, is placed in the top of the car upon theplates 16 of the grate bars. The car is then shifted along the tracks 22upon the draft. opening into the end of a suitably positioned fixedsuction tube 23'. After the car has been coupled with the suctiontubethe charge of ore is ignited, any suitable means being employed forthispurpose as for example the usual flame igniter, not shown, and afterthe burning of the -lore is started it is maintained through the draftofair drawn therethrough by the suction means connected with the suctionpipe'23.

By employing'the perforated plate 17 the draft through the charge isequalizeduand this is furtherimproved by the use of the slotted plate19. The suction is thus made uniform over the entire grate bar surfaceand results in the production of a uniformly sintered product, the fumesfrom which are of sufficient sulphur dioxide concentration to be usedfor the manufacture of sulphuric acid.

Having thus described my invention, what I- claim is:

-1. An ore sintering car, comprising a body having bottom, side and endwalls, means for coupling a suction tube with one wall for the cremovalof air from the interior of the car,

2. A sintering car, comprising a Wheel supported body'having bottom,side and end walls, one of said walls having an. aperture therethrough,means surrounding said aperture for facilitating the coupling ofa'suction pipe with the wall, a lining disposed about the inner surfaceof the side and end walls at the upper portion of the car, a atestructure-within the upper portion 0 the car inthe area between thelined walls, and a perforated draft equalizing plate disposed within thebody beneath said'grate structure, said grate structure being designedto. support burning ore.
